` steel Wool pad nds very valuable and important applications tocleaning, scouring, or partially resurfacing floors, decks, tables,counters and vother like surfaces, especially in hospitals, schools.factories and ships. The creation of flying dust, as occurs in othertypes of re-surfacing or scour-A ing machines is greatly reduced by theuse of my Y annular steel wool pad and may be eliminated entirely bycombining, with theV rotary machine, a'dust-collecting ldevice such asthe Vacuum suction mechanism Wellknown in the art.
